Obvious synergistic effect.
Embodiment
In order to understand the present invention, the present invention is further illustrated with embodiment below, but be not limited to embodiments of the invention.
Prevention effect of the composition of the TrinexAN_SNacethyl of embodiment 1 and chitosan oligosaccharide to wheat diseases
Single compound or the dissolving of composition solvent are prepared into 1000mg/L mother liquor.It is pre- according to biological activity determination
Experiment, a certain amount of above-mentioned mother liquor is diluted with 0.1% Tween 80, is configured to the concentration needed.During experiment, jointing is selected respectively
There are the different fields that white powder disease and wheat rust occur phase.Single dose and the combination of manual sprayer same concentrations is respectively adopted
Each 1 time of thing routine conventional spray, 20 plants is sprayed per chemicals treatment, and set blank control.Sprayed again 1 time every 10-15d after medicine.Respectively
In 7-10d investigation disease refers to before medicine and after the 2nd dispenser.Powdery mildew investigates every plant of whole blade, and leaf, which becomes rusty every plant, investigates 3, top
Leaf, with lesion area on every leaf account for whole leaf area percentage be classified, by the following method carry out the classification of blade powdery mildew and
Blade rust is classified, and calculates disease index and preventive effect.
Powdery mildew blade staging：
0 grade：It is disease-free
1 grade：The connected area of scab accounts for less than the 1% of whole leaf area；
3 grades：The connected area of scab accounts for the 1%-10% of whole leaf area；
5 grades：The connected area of scab accounts for the 11%-20% of whole leaf area；
7 grades：The connected area of scab accounts for the 21%-50% of whole leaf area；
9 grades：The connected area of scab accounts for more than the 51% of whole leaf area；
Rust blade staging：
0 grade：It is disease-free；
1 grade：Lesion area accounts for less than the 5% of whole leaf area；
3 grades：Lesion area accounts for the 6%-25% of whole leaf area；
5 grades：Lesion area accounts for the 26%-50% of whole leaf area；
7 grades：Lesion area accounts for the 51%-75% of whole leaf area；
9 grades：Lesion area accounts for more than the 76% of whole leaf area；
Composition is shown in Tables 1 and 2 to the prevention effect of wheat powdery mildew and wheat rust.
Effect of the composition of the TrinexAN_SNacethyl of table 1 and chitosan oligosaccharide to wheat powdery mildew
Effect of the composition of the TrinexAN_SNacethyl of table 2 and chitosan oligosaccharide to wheat rust
From table 1, the composition containing TrinexAN_SNacethyl and chitosan oligosaccharide is 7 in proportioning:1、1:1、1:When 7, composition and phase
When to answer single dose concentration be 40mg/L, composition is above the preventive effect of the single dose under same concentration to the preventive effect of wheat powdery mildew, says
Bright composition is synergy.
From table 2, the composition containing TrinexAN_SNacethyl and chitosan oligosaccharide is 3 in proportioning:1、1:1、1:When 3, composition and phase
When to answer single dose concentration be 20mg/L, the reality that composition is above the single dose under same concentration to the actual preventive effect of wheat rust is prevented
Effect；In addition, being calculated by synergy, matched in the composition of TrinexAN_SNacethyl and chitosan oligosaccharide as 2:1、1:1、1:When 2, composition
Actual preventive effect to wheat rust is above the theoretical preventive effect of composition, and it is synergy to illustrate composition.
Effect of composition of the embodiment 2 containing TrinexAN_SNacethyl and chitosan to turfgrass Bermuda grass leaf spot
Single compound or the dissolving of composition organic solvent are prepared into 1000mg/L mother liquor.Surveyed according to bioactivity
Determine trial test, a certain amount of above-mentioned mother liquor is diluted with 0.1% Tween 80, be configured to the concentration needed.During measure, first by decoction
Spray on potted plant Bermuda grass weeds, be then quantitatively inoculated with after leaf spot opportunistic pathogen, moisturizing culture 24h, be placed in greenhouse and cultivate, one
The percentage that plant leaf surface infects is estimated after fixing time.Using Abbot formula, percentage is converted into preventive effect.
X is the preventive effect of active component A when concentration is a, and y is the preventive effect of active component B when concentration is b.
Compare theoretical effect and actual effect, evaluate the synergy of composition, make when being more than theoretical preventive effect using actual preventive effect as synergy
With.It the results are shown in Table 3.
Effect of composition of the table 3 containing TrinexAN_SNacethyl and chitosan to Bermuda grass leaf spot
It is 4 in composition proportioning as seen from Table 3 by potted plant test:1、1:1、1:When 4, chitosan-containing and TrinexAN_SNacethyl
Composition is above the theoretical inhibiting rate of composition under same concentration to the actual inhibiting rate of Bermuda grass leaf spot, illustrates that composition is
Synergy.
It is 5 in the weight ratio of chitosan and TrinexAN_SNacethyl in addition, being found by experiment of dressing seed:1、2:1、1:1、1:2、1:10
When, composition is high compared with the effect of the corresponding single dose under same dose to Bermuda grass leaf spot, powdery mildew, the preventive effect of rust, fills
Bright composition of defending oneself has obvious synergistic effect.
